Energy and environment has gained traction within the field of entrepreneurship literature, but a comprehensive empirical study that examines the relationship between the cost of energy and small- and medium-sized enterprise (SME) innovation is an omission. Therefore, this novel study aims to examine the relationship between the cost of energy and SMEs innovation in Sub-Saharan Africa (SSA) by first examining the differential impact of the various generation sources on the price of electric energy. This research has enabled us to investigate and understand the transmission mechanism of increasing/decreasing electricity price on innovation decisions and activities of SMEs in SSA.

Using quantitative approach, with the data from the World Bank Enterprise and Innovation Follow-up Surveys, the study utilises a Tobit model to test whether the generation mix (renewable and non-renewable generation sources) increases or decreases electricity prices and examine the impact of the cost of electric energy on SMEs innovation in SSA.

The findings of this study shows that the cost of electricity affects negatively on SMEs innovation decision and activities of SMEs in SSA. The impact of renewables on the price of electricity has a larger magnitude relative to that of non-renewables. This finding has implications for policy makers promoting renewable energy without a policy design to tackle the unintended price effect of promoting renewable energy.

This is the first study to introduce cost of energy into an innovation model and to empirically examine the role of cost of energy for innovation activities of SMEs in SSA. Further, it examines the sources of generation on electricity price in SSA. The study contributes towards the empirical literature, and the findings also have implication for policy makers regarding the unintended consequences of promoting the transition to low-carbon electricity generation sources on SMEs via the cost of doing business implication.

The study aims to explore the impact of National Health Insurance Scheme (NHIS) enrolment on farm investments in a developing country setting. We classify farm investments into (1) soil and land investments and (2) hired adult labour.

This study used data on 5,883 farm households from the sixth round of the Ghana Living Standard Surveys (GLSS), which is nationally represented data at the household level. The data also includes a Labour Force Survey module. The sample frame was divided into a primary and secondary sampling unit, with interviews taking place in 1,200 enumeration areas (EAs). The estimation of impacts was carried out using ordinary least squares (OLS) estimations and addressed endogeneity concerns using propensity score matching (PSM) and instrumental variable (IV) estimators.

The study finds a strong positive association between the NHIS enrolment status of farm households and investments in agricultural land and soil health improvement. Precisely, farm households who are enroled in the health insurance system tend to invest about 32% more in soil and land improvement activities and 30% more in hired farm labour than households who are not enroled in NHIS.

The overall evidence from our study suggests that instead of high investments in fertilizer and other input subsidy programmes in Africa, sustainable smallholder agricultural investments can be achieved if concerns and issues of farmers’ health coverage are adequately addressed.

This is one of the first papers that have explored the impact of NHIS in developing countries on farm investments.

The purpose of this paper is to examine the relationship between financial literacy, access to finance and growth among small- and medium-sized enterprises (SMEs) within the Midlands region of the UK. It assesses whether financial literacy assists SMEs to overcome information asymmetry, mitigates the need for collateral, optimizes capital structure and improves access to finance.

To gain a deeper insight into the complex relationship between financial literacy, access to finance and growth, a qualitative research is carried out among SMEs that have operated for over five years or longer. Using the purposive sampling technique, 37 firms were selected based on size, location and characteristics, mainly from the city of Birmingham and the joining conurbations. Open-ended and a combination of dichotomous questions were used for the survey. Interviews were recorded, transcribed and thematically analyzed.

Financial literacy is an interconnecting resource that mitigates information asymmetry and collateral deficit when evaluating loan applications, therefore financial literacy should be part of school curriculum. The analysis suggests enhanced financial literacy, reduces monitoring cost and serves to optimize firms’ capital structure that positively impacts on SMEs growth. Financial management knowledge is recognized as the core resource that aids an effective decision making by owners of SMEs.

The limitation of this research is the small sample that limits its generalization. Its findings could be enhanced by a larger sample and by conducting comparative studies in other regions or economies. SMEs growth is seen as a strategic policy to stimulate enterprise but the finance gap tends to constrain that objective. The UK Government’s effort to improve access to finance and to mitigate excessive collateral demands by lenders has proved elusive. This empirical research provides evidence that financial literacy enhances access to finance and, in turn, promotes growth potentials.

The results of this study advocate the provision of financial literacy at schools and target support for SMEs to acquire financial management skills in order to mitigate information asymmetry between lenders and borrowers.

Findings suggest that financial literacy mediates access to finance, enables enterprises to use optimal financial structure to mitigate business failure, creates employment and reduces public sector support for social benefits.

This study is novel in that it examines financial literacy and its implications for access to finance and firm growth in the UK. The study is an effort to highlight the role of financial information in mitigating barriers to finance for SMEs.

Expert systems are computer-based systems that mimic the logical processes of human experts or organizations to give advice in a specific domain of knowledge. Fuzzy expert systems use fuzzy logic to handle uncertainties generated by imprecise, incomplete and/or vague information. The purpose of this paper is to present a comprehensive review of the methods and applications in fuzzy expert systems.

The authors have carefully reviewed 281 journal publications and 149 conference proceedings published over the past 37 years since 1982. The authors grouped the journal publications and conference proceedings separately accordingly to the methods, application domains, tools and inference systems.

The authors have synthesized the findings and proposed useful suggestions for future research directions. The authors show that the most common use of fuzzy expert systems is in the medical field.

Fuzzy logic can be used to manage uncertainty in expert systems and solve problems that cannot be solved effectively with conventional methods. In this study, the authors present a comprehensive review of the methods and applications in fuzzy expert systems which could be useful for practicing managers developing expert systems under uncertainty.

The purpose of this examine the impact of income inequality and shadow economy on environmental degradation given the growing income inequality, shadow economy and ecological degradation in developing countries. Thus, this study is motivated to offer empirical insight into how income inequality and shadow economy influence the environment in African countries.

Data from 29 countries in Africa between 2000 and 2017 were used, while the novel method of moments quantile regression of Machado and Silva (2019) and Dumitrescu and Hurlin (D-H) (2012) granger causality is used as the estimation techniques.

The results established the presence of cross-sectional dependence and slope heterogeneity in the panel, while Westerlund panel cointegration confirmed the long-run cointegration among the variables. The results from the quantile regression suggest that income inequality increases environmental degradation from the 5th to the 30th quantiles, while from the 70th quantiles, income inequality reduces ecological degradation. The shadow economy negatively influences environmental degradation across the quantiles, strengthening environmental quality. Per capita income (economic growth) and financial development positively impact environmental degradation throughout the quantiles. However, urbanization reduces environmental degradation from 60th to 95th quantiles. The D-H causality established a two-way relationship between income inequality and environmental degradation, while one-way from shadow economy, per capita income and urbanization to environmental degradation were established.

This study provides fresh insights into the nexus between shadow economy and environmental quality in the presence of higher levels of income inequality for the case of African region. The study applies quantile analysis via moment proposed by Machado and Silva (2019). This technique shows that the impact of income inequality and shadow economy on environmental degradation is heterogeneous across the quantiles of ecological footprints in Africa.

Entrepreneurial orientation is among the vital factors that contribute to performance, especially for small and medium-sized enterprises (SMEs). However, the empirical studies provide mixed results and call for new studies to examine this relationship. Therefore, this study aims to determine the entrepreneurial orientation's (EO) direct and indirect impact (via entrepreneurial competencies) on firm performance. Additionally, the moderating role of environmental dynamism is also tested in entrepreneurial competencies and firm performance relationships.

The data (N = 332) were collected from managerial rank employees, using a self-administered questionnaire, working in different SMEs in Pakistan. In addition, structural equation modeling (SEM) was executed using SmartPLS 3.2.

The study's results demonstrate that EO positively influences entrepreneurial competencies and firm performance, and entrepreneurial competencies also mediate the relationship between EO and performance. Additionally, environmental dynamism strengthens the positive relationship between entrepreneurial competencies and performance.

This study identifies that entrepreneurial competency is the missing link between EO and firm performance, due to which the relationship between them is indecisive. This study also contributes to the contingency perspective by explaining the role of environmental dynamism as a boundary condition in strengthening the relationship between entrepreneurial competencies and SMEs' performance in an emerging economy.
